RX Watt is redefining wireless sensing by delivering complete RF power and data transfer solutions for next-generation Internet of Things (IoT) applications. At the heart of its technology is the ability to wirelessly transmit energy and communication signals to sensors that require no battery, enabling maintenance-free deployments in industries from rail to manufacturing. The company’s modular hubs deliver long-range RF power (10 to 30 m), while receiver modules support ultra-low-power sensing and standard interfaces such as BLE, creating a seamless bridge between power and data.
Technology driving sustainability
RX Watt leverages custom silicon IP and advanced antenna design to achieve best-in-class RF energy harvesting efficiency and sensitivity. Its system supports simultaneous power delivery and data communication, allowing a single RF receiver to both charge the sensor and relay data, dramatically reducing complexity in sensor networks. The platform is ideal for industrial environments, offering rugged RF hubs and context-aware antennas that operate in harsh conditions. Beyond functionality, RX Watt has baked sustainability into its mission by eliminating disposable batteries and enabling wireless power transfer; it significantly lowers the e-waste footprint of large sensor fleets, supporting full life-cycle assessments (ISO 14040) of carbon savings.
First Wireless Power & Data Transfer Gateways
Applications and impact
The RX Watt’s technology is being applied across sectors such as battery-free sensors for rail carriages, logistics tracking, infrastructural monitoring, and wearable health devices. For example, RX Watt’s sensors have been deployed in real-world trials on railway rolling stock, demonstrating how RF-powered nodes can capture vibration and temperature data without wiring or battery change-outs. With growing demand for maintenance-free IoT devices and sustainable sensing networks, RX Watt positions itself at the intersection of wireless innovation and environmental responsibility.
About RX Watt
RX Watt Ltd is a spin-out from the University of Glasgow’s GREEN Electronics Lab, incorporated in October 2023. Leveraging over five years of R&D and backed by a UK IC Research Fellowship and government support, the Glasgow-based company develops integrated solutions for RF-powered sensing, wireless charging, and communication hubs. By removing batteries from large-scale sensor deployments, RX Watt supports high-reliability monitoring across global IoT networks while actively reducing carbon and waste footprints.
